Answer:
The answer to the question: What did Chief Watie and Chief Ross disagree over regarding freedmen, would be: whether freedmen were to be granted citizenship to the Cherokee Nation, and whether they should be granted rights, properties and lands, just like any other Cherokee.
Explanation:
Slavery of African Americans was not just an issue of whether a person was white, or Native American. The truth is that both whites and Native Americans, especially those members of the Cherokee nation, were slaveholders. Funnily enough, statistics show that at some points, the Cherokee had more slaves than even whites in some states. However, at the end of Civil War, and under force by the U.S government, the Cherokee from the North faction, led by Principal Chief John Ross and those of the South, led by Chief Stand Watie, met. While the group of the North agreed with their Union counterparts that slavery should be ended, and freedmen should be granted full rights as citizens of the Cherokee Nation, those from the South were willing to free slaves, but these were to be moved from Cherokee territory and placed on U.S territory. In the end, John Ross´s proposal was the one accepted, and the treaty was signed.
